MACHINE FOR- CUTTING one AND rnnranmc- STOCK srnrrs.

.Application filed Ju1y 2, 1934. Serial no. 723,612;

My invention relates to improvements in machines adapted to cut off long lengths of stock into desired lengths, and at the same time perform operations on the severed.

parts which will prepare them for use.

Specifically my invention is used for preparingtire flaps such as are used between the inner tube and'the outer tire, and the in vention cuts a long strip of stock into desired. lengths, skives' or thins; the severed Parts at both sides of the point of severance thus preparing two end portionsot flaps at once,. punches the valve hole in the tlap,-and if desired'prints upon the flap'directions for its use. The machine is intended to do this work advantageously and rapidly, and from the description which follows itwill be seen that while the machine as illustrated is particularly adapted for the preparation of tire flaps, it might be used for many other purposes-where a stock strip is severed and treated in a manner analogous to thatillustra-ted.

i In order that the work may be carried on accurately and without loss of material, I provide an intermittent teed, andarrange the operating parts so that when the feed stops, the stoclrwill be cutoff, and the severed strip or flap cut, skivedand punched, and if desired printed. Another object of my invention is to produce a machine of this character having means stated for cutting oii' and preparing the stock,- together with .a lock which will lock the stock feed against movement in either direction, while other work is being done, and further to,

provide means for adjusting the feed to produce fiapsor stock strips of different lengths, and, likewise have the adjusting 'means operate in relation to the locking means so that the locking and adjusting means'will both be simultaneously placed to properly co-operate; I My invention is intended furtherrto produce a means for holding the stock firmly while it is being cut and skived or thinned, and yet in a manner which will be convenient to permit the proper feeding of the main strip. These and other advantages will appear from the.

description which follows.

Reference istobe had tothe accompanyingv drawings-forming a partoi thisspecifi cation, in whichsimilar reference characters indicate corresponding parts in all the views.

Figure 6' is a cross section on the line 6-6' "Figurelis a View similar to Figure 5 but 'view illustrating the manner in which the stock is cut oil' into flaps or strips.

The machine is provided with a suitable frame 10 which can beef any designicapable of carrymgthe operatmgpartaand at one end has preferably a bracket 11 at the upperend of which is journaled a stud lZcarry iug the roller 13 on which is placed thedrum' l l which carries the longstock strip '15 from which the flaps are prepared. For the par-' ticular use referred to, rubberized cloth or canvas is generally used, and it comes on drumslike the drunr l4, and the roller 13 is adjusted with relation to the drum so to hold thedrum correctly by means of the bolt attachmentslo which are carried by "the roller and engage the inner wall of the drum. Obviously any usual or suitable means cairbe used for adjustingand tight ening the drum on the roller, and likewise the drum might be supported independently. from the machine, or the longstock -'stri.ps

might be fed to thefmachine in anysuitable way without atlectingthe invention. a

The stock in strip form is carriedthrough the machine by thepairs 01" teed wheels 17 and '18 which are ispaced apart horizontally and arranged one above the other vertical.-

ly in a mannercustomary with teed wheels, and they have a uniform drive, but the wheels 18 are preferably slightly larger than the wheels 17 so as to hold'the stock under. tension while it 1s being printed on andpunched. hereinafter described." This is necessary because the stock is usually con-' vex on one side and concave on the other, and in any event it has a tendency to curl and cannot be well operated on unless it is held tautand fiat.

The upper and lower feed wvheels are preferably movable with relation to each has a plurality of mutilated driving gears 22 23 and 24C althou 'h a reater or less 7 7 C) t') number may be used. These gears have veach teeth on one side and a plain surface on the-other as shown in Figure 9, and the number of teeth variestoprovide for driving the feed wheels a distance proportional to the flaps or stock strips to be cut off, as

will presently appear. The gear 22 is shown connecting with a pinion 25 on the countershaft 26 (see Figure 1) and this drives both pairs of feed wheels, the connection to the feed wheels 17 being by means of a bevel pinion 27, the bevel pinion 28 on the lower feed'wheel shaft 29, the pinion 30. the vertical shaft 31, the pinion 32, and the pinion 33 on theupper shaft 34. mounted in a box 17 which slides on and is keyed to'the shaft 31 and moves in'a slot 17 at the upper end of its support. The

connection with the feed wheels 18 is exact ly similar to that just described, and the corresponding parts are marked 27 28 etc.

Thus itwill be seen that both sets of feed wheels comprising the stock feed are simi larly driven and must have the same movement. The pinion 25 is keyed to the'shaft 26 and by moving it into connection with the desired drive gear 22, 23 or 24, which have different numbers of teeth, it will be seen that a greater or less movement will be given to the feed wheels or rolls, the desired move ment depending on the length of strip which I is to be cut from the main stock strip. To

effect this movement a suitable shipper 35 is used, having a fork 36 to engage the pinion 25, and having an arm 37 to move the cams 22 23 and 24. which correspond to the gears 22, 23 and 24;, and which are keyed to the shaft 19 as shownin Figure 1., Thus when the gear 25 is moved into engagement with a desired mutilated drive, the corresponding cam will be similarly moved so as to engage its actuated mechanism which locks the'feed wheels as presently described. It-will be noticed by reference to Figure 9 This shaft is that the feed wheels are at rest. during half the rotation of one of the gears 22, 23 or 2%,and during this idle moment of the feed the wheels are locked and the cutting'and on a link aliagainst. the tension of a spring 4-2, and the link connects by meansof av bell crank 43 (see Figures 1 and 2) with a red 41 1 which is pivoted to the pawl 15, this in turn being pivoted to suitable support a6 and arranged to engage the notches 47 on a locking wheel 49 attached to the shaft 29 On the opposite side of the locking wheel is a pawl 4tS'acting as a detent, this being pivoted as shown at 51 and held against the wheel 49 by a spring 52. There are preferably as many teeth 47 on the wheel 49 as there are teeth on the driving pinion25, so that whenever the feed wheels stop, the pawls 15and 48 will engagein their respec! tive notches and lo'ck' the wheels against for-- ward movement by momentum or backwards. I have shown this lockingarrangement connected toone of the feed wheels, but in practice I prefer to connectit with both sets of feed wheelsso as to distribute the strain, and the connection could be like that indicated, or other locking means might be used. 4: As the stock 15 is fed through the machine, it passes through suitable guidingdevices 53 and is punched at appropriate distances by the punch 54 whichis not shown indetail but which can be any approved type'of punch having an adjusting device 5 1 and being arranged to punch. a hole through the strip so that a valve stem or the like can be inserted and no subsequent punching will be required. The punch can be actuated. during the interval that the feed is at rest,- and can be driven in any suitablemanner. As shown it has a stud 5 5 driven by a sprocket wheelv 56, and this connects by a chain 57 with a sprocket wheel 58 on the shaft 59 which issuitably mounted on the machine frame parallel with the shaft 63 from which it is driven, the connection being by means of the sprocket wheel 60, chain belt 61, and sprocket wheel 62. It will be seen that when the teeth of one of the mutila ted gears 22, 23, etc., engage the pinion 25 to I drive the feed wheels, the plain face of the said gear will be opposite the pinion 6 1, and so the punch will not be operated; but when the plain face of the gear is, opposite the pinion 25, the teeth will engage. the. pinion 64. and operate the punch. After leaving the feed wheels 18, the stock strip 15 passes over a bed 65 which is ieo supportecl or; the n ain frame and {lllCll is slotted as shown at 66 in'Flg ure 5, and 1s provided w th a tra sverse slldeway 67 n which a sliEle GS lilOYi-ZS transversely, this slide having; a part 68, mov ng 1n the slot- 60 audifhaving oh the guz ier an esteu sion 'shoivn' i Figures 5, "7' and 8. The slideGS has at one end'a, fork between the "arms of l wh ich is pivoted a cutter '51 \yhich is a rapidly rotating buzz cutter of any suitable ipe, largest in thee-enter and taperihg towarcls the ends as shown clearly vflligij res4 aucl fi, and it may be driven in ,anysi'iita ble manner as vfor iustarice by the flexible shaft 72; It will be see/ 11 by relierchceto Figure that when thislt /m cutter is forced transverselyacross the stock 7 15," it Will sever the stock alid will also ski ve or the adjacent e ucl portiops of the stock near the l ne of severance, as shown at 15%."1 Thus as the main steel; strip is severed t vvo eiidparts of two stock strips or the slide 68 with the crank 75 on 'the shaft flaps are simiiltaneou sly arid nicely skivecl. The out oil" device ,by means o'f'whrch the stock is severed ismoved backvvaru fillet forward. of the stock by means of a pltman 74; Which connects a stud 73 on 59v hereinii eferi'eci to so that the same shaft simultaneously iiioves the] cut-off cleviee v backwar'cl,laud"forward across the stock anti As previo sly remarked, thestOCk, hile being punched, is held under tension by "reason (it: the: diameter Oil the Wheels 17 ancl 18, but at the point} Where it:
